The obvious question is why? There are a ton of reasons why not (weight, more driveline mass, space constraints on a front midship platform), and not a whole lot of benefits.

When Audi debuted the Quattro system it was designed for Group A and B rally cars, and dominated there and were great in Le Mans. Chevy doesn't rally race the Vette, and has dominated Le Mans with RWD, why change?
